It is strongly recommended to use genuine Atlas Copco Lubricants. They are the result of years of field
experience and research in our labs. See section Preventive maintenance schedule for replacement intervals and
section Service Kits for part number information.
Roto-Inject Fluid
Atlas Copco’s Roto-Inject Fluid is a specially developed lubricant for use in single stage oil-injected screw
compressors. Its specific composition keeps the compressor in excellent condition. Roto-Inject Fluid can be used
for compressors operating at ambient temperatures between 0 °C and 40 °C. If the compressor is regularly
operating in ambient temperatures between 40 °C and 46 °C , oil lifetime is reduced significantly. In such case it
is recommended to use Roto-Xtend Duty Fluid.
Roto-Xtend Duty Fluid
Atlas Copco’s Roto-Xtend Duty Fluid is a high-quality synthetic lubricant for oil-injected screw compressors
which keeps the compressor in excellent condition. Because of its excellent oxidation stability, Roto-Xtend Duty
Fluid can be used for compressors operating at ambient temperatures between 0 °C and 46 °C .
Roto-Xtend Duty Fluid is the standard oil for compressors equipped with freeze protection.
Roto-Foodgrade Fluid
Special oil, delivered as an option.
Atlas Copco’s Roto-Foodgrade fluid is a unique high-quality synthetic lubricant, specially created for oil-injected
screw compressors that provide air for the food industry. This lubricant keeps the compressor in excellent
condition. Roto-Foodgrade Fluid can be used for compressors operating at ambient temperatures between 0 °C
and 40 °C .
8.4 Oil and oil filter change
Warning
8.3 Oil specifications
Never mix lubricants of different brands or types as they may not be compatible and the
oil mix will have inferior properties. A label, indicating the type of oil filled ex-factory, is
stuck on the air receiver/oil tank.
Always drain the compressor oil at all drain points. Used oil left in the compressor can
contaminate the oil system and can shorten the lifetime of the new oil.
The operator must apply all relevant Safety precautions.
If the compressor is equipped with an Energy Recovery system, also consult Maintenance
for Energy Recovery Systems.
